摘要：
The sound of the tube amp due to the harmonic distortion has been thought to depend not only on the vacuum tube type but also on the vacuum tube manufacturer and individual differences. However, quantitative differences in tube characteristics of the manufacturer have yet to be revealed. In this study, the characteristics of the triode 12 AX 7 of the five major manufacturers were analyzed based on statistical analysis of advanced physical model parameter sets. Tube characteristics were divided into three groups by cosine similarity and group clustering method. As a result, we succeeded for the first time quantitatively combining tube distortion characteristics and tube characteristics. © 2020 The Institute of Electrical Engineers of Japan.
